## 📜 **TL;DR:**

* Move your BTC to Hemi by using the Bitcoin Tunnel, enabling interactions within the Hemi Network ecosystem with Bitcoin assets.
* An [EVM](https://docs.hemi.xyz/how-to-tutorials/using-hemi/wallet-setup/metamask-wallet-setup) and [BTC](https://docs.hemi.xyz/how-to-tutorials/using-hemi/wallet-setup/btc-wallet-setup) wallet are required to move BTC assets via the Bitcoin Tunnel.
* A minimum of `0.0001 BTC` is required to deposit and withdrawal using the Native Tunnel.
  {% endhint %}

## 🏁 Prerequisites

* **Acquire BTC** - BTC can be purchased on any number of exchanges and on-ramps. 
* [**EVM (MetaMask) Wallet Setup**](https://docs.hemi.xyz/how-to-tutorials/using-hemi/wallet-setup/metamask-wallet-setup) **-** Set up your EVM wallet and add Hemi Network.

**TESTNET ONLY**\
\
If you plan on developing on or interacting with Hemi testnet, alternative prerequisites may apply. To test out the Bitcoin Tunnel on testnet, you can obtain tBTC (Testnet Bitcoin) via the [**Direct Faucet Access**](https://coinfaucet.eu/en/btc-testnet/)**.**

### 3. Connect your EVM wallet

Currently, MetaMask and Rabby are the only EVM wallets Hemi supports. Our team is working to add  support for additional wallets.

{% hint style="info" %}
Connecting an EVM wallet is required for the initial version of the Bitcoin Tunnel. The address connected will receive the tunneled Bitcoin assets.&#x20;
{% endhint %}

### 8. You have successfully tunneled BTC to Hemi! 🎉

Your transaction has been initiated and must go through two confirmation periods to confirm your deposit:

1. Withdrawal from BTC address (\~1hr) - When you initiate a deposit request, a transaction is signed from your BTC address to transfer the specified amount into a secure vault on the Bitcoin network. This deposit requires six block confirmations, which generally takes about one hour to complete.
2. Deposit into EVM Hemi address - Once the deposit is fully confirmed on the Bitcoin network, the Hemi Network validates the transaction and mints a corresponding token receipt (`hemiBTC`) on the Hemi blockchain, ensuring a seamless transition of assets.

You can check the status and view the transaction in the `'Transaction History'` tab.&#x20;

<figure><img src="https://3063395300-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FBrGAUP9hcnvqWQvHZlN0%2Fuploads%2FQZpdrIVHGkOxOBHRpX57%2Fimage.png?alt=media&#x26;token=af3037ce-f3fe-4eca-9ad5-a233ab2a700a" alt=""><figcaption></figcaption></figure>

{% hint style="success" %}
`hemiBTC` can be tracked and added to your wallet at the following contract address: **`0xAA40c0c7644e0b2B224509571e10ad20d9C4ef28`**
{% endhint %}

#### Manual confirmation of deposit

After six confirmations, Hemi can confirm a successful deposit from the Bitcoin network and deposit the funds to your address. Occasionally, the vault operator will require a manual confirmation in order to complete the deposit.&#x20;
